Hi,
Thanks to Matthew Stier, Darren Dunham, Jay Lessert, and Kris Briscoe for
their answers.
Short answer (and consensus) is: no.
A while ago, I asked:
> I will soon need to add a dual port SCSI board with a D1000 storage device
> to a Sun Ultra Enterprise 450, running Solaris 2.6 with SDS.

> The machine currently has 20 internal disk slots (18 full) and two external
> D1000 devices, each with 12 disks. The PCI slot layout is as follows:
> 10: empty
> 9: empty
> 8: empty
> 7: Sun Gigabit ethernet board
> 6: dual port SCSI board connected to external D1000
> 5: dual port SCSI board connected to internal disk rack
> 4: dual port SCSI board connected to external D1000
> 3: empty
> 2: empty
> 1: dual port SCSI board connected to internal disk rack
>
> The dual port SCSI boards are all Symbios 53c875.

In Matthew's words:
SunOS keeps a flat file database of devices, mapping their OBP path, to an
OS instance. The file is /etc/path_to_inst, and unless you remove the instances
for existing devices, you won't run into any conflicts.
> Any words of advice on which slot to use for the new board ?
None received.
Regards,
Christian
